Don't be too hard on yourself. Quitting smoking can be difficult so you might have to try a few times before you're successful. Research has shown that trying but failing to quit can lead to more attempts in the future, and that it often takes multiple attempts to finally quit smoking. These include nicotine replacement therapy products. They provide controlled amounts of nicotine, to reduce smoking withdrawal symptoms and cravings. Two types are available by prescription a nicotine nasal spray and a nicotine inhaler. Three types can be bought over-the-counter nicotine gum, skin patches and lozenges.
